No. way.
Am I the only one getting increment (before conversion) coming to Sg?

I don't have any room rental written contract with my houseowner. HDB detail submission is not rental contract.

It depends on your lifestyle. You only need less than 1500sgd for basic needs exclude car loan and house mortgage.
I can do nothing with my 50% saved in Msia. But I can achieve a lot with the 65% saved here. I know some friends who fly every weekend for backpacking or couchsurfing.

Since you do not want to simply change job in Sg (it's troublesome for non PR), you should look into job scope and its contribution to your career development as well. IMO without taking any other thing into consideration, I won't take 3.7 to 2.9 offer.

My gf got offered 2.5k sgd as freshgrad (she just graduated this June). She rejected it because of the job scope.

Horticulture Science dean list graduate from UPM just for your reference on Sg price tag/job opportunity.

Walk/bus to Hougang Central MRT. NorthEast line to Outram Park MRT, change to East West line to Tanjung Pagar. At least 40mins.

Train is convenient and fast. Your 54 mins probably due to extra distance needed to walk/bus from exact location in hougang ave8/tanjung pagar.

I don't remember having all these during my fresh grad days...
Eliteness detected.

Job that prefers Sg and PR will have the requirement stated there. In my case, the headhunters/employers were browsing through Malaysia database so there was no such expectation. For freshgrads, the hiring manager requires English transcript, and official letter stating your graduation. They are sufficient to get you employed in Singapore even though you're not yet receive your cert, or held your convo.

Pure technical jobs are highly competitive due to high supply from India/Philippines. Hybrid job which requires similar culture in critical thinking and communication skill (e.g. techincal sales, auditors) give Malaysian the highest advantage.
